5.1.2 Programming with USB Bootloader: Device Firmware Upgrade (DFU)

The Atmel AT90USB1287 AVR comes with a default factory pre-programmed USB bootloader located in the on-

chip boot section of the AT90USB1287. This is the easiest and fastest way to reprogram the device directly over

the USB interface. The FLIP PC Application, available for free on the Atmel website, offers a flexible and user

friendly interface for reprogramming the application over the USB bus. FLIP can be found at the following hyperlink:

http://www.atmel.com/tools/flip.aspx

The “HWB” push button is used to place the AVR into DFU mode after reset. Refer to the Atmel

AT90USB1287

Datasheet

for further information.

The following steps enable the ATMembase DFU mode:

1. Press and hold “HWB” button
2. Press the “RESET” button
3. Release the “RESET” button
4. Release the “HWB” button

HWBE fuse must be enabled to support DFU

The use of external USB hubs can induce inconsistent programming behavior of the

ATMembase. Therefore, it is recommended to connect the ATMembase to a USB

port that is directly connected to the user’s computer during Flip DFU programming.

For more information related to the USB bootloader and the use of FLIP software, please refer to Application Note

found at the following hyperlink:

5.1.3 Program debugging with the Atmel JTAGICE III

The AT90USB1287 can be programmed using the specific JTAG link. This subsection will explain how to connect

and use the Atmel AVR JTAG ICE.

When the JTAGEN fuse is disabled, the four TAP pins are normal port pins, and the

TAP controller is in reset. When the JTAGEN fuse is enabled, the input TAP signals

are internally pulled high. This enables the JATG for boundary-scan and program-

ming. The Atmel AT90USB1287 device is shipped with this fuse programmed
